2. Multiple Satellite Horizontally Tiered Topology

For very large networks, a more distributed method may be needed, such as having multiple

RHN Satellite Servers in a horizontally tiered configuration and balancing the load of client

requests.

It is possible to synchronize content between RHN Satellites using the

rhn-satellite-exporter and satellite-sync -m commands. This feature is discussed in

detail in Section 1.1, “rhn-satellite-exporter”.

Additional maintenance is the biggest disadvantage of this horizontal structure.

3. Satellite-Proxy Vertically Tiered Topology

An alternative method to balance load is to install RHN Proxy Servers below a RHN Satellite

Server. These Proxies connect to the Satellite for RPMs from Red Hat Network and custom

packages created locally. In essence, the Proxies act as clients of the Satellite.

This vertically tiered configuration requires that channels and RPMs be created only on the RHN

Satellite Server. In this manner, the Proxies inherit and then serve packages from a central

location. For details, refer to the RHN Channel Management Guide.

Similarly, you should make the Proxies' SSL certificates clients of the Satellite while also setting

them to serve the client systems. This process is described in the RHN Client Configuration

Guide.
